One of the most spectacular features of karst topography is a cave, like those from Carlsbad National Park. This picture shows a cross-sectional view of a cave, where you can see some features of caves, like an underground lake, stalactites, and stalagmites. Can you distinguish between the stalactites and stalagmites in the picture? Roll over the image with your mouse to see if you are right.
